I've noticed that I consistently experience vivid, visceral dreams when taking brief mid-day naps (usually ~20m at 8h after waking). They're not bad, just intense.
I wonder why—maybe I just remember them better during day? My night-time dreams are usually mild or absent.

Do you wear a sleep mask? I wonder if the light shining through your eyelids could have something to do with it
